What food web do penguins belong to?

Penguins belong to the Antarctic food web. This food web is centered around the krill, a small shrimp-like creature that is the primary food source for many animals in the Antarctic. Penguins feed on krill, as well as other small fish and squid. They are in turn preyed upon by larger predators, such as seals, whales, and leopard seals. The Antarctic food web is a complex and delicate system, and any changes in the environment can have a ripple effect on the entire ecosystem.
